Akhos, The Sword of Weight

The bronze Gladius Tyrvaard carries has been enchanted by the Spirits to be very heavy to any but the wielder. Tryvaard (or any others who use the blade) will find the sword light and easy to wield. Those on the receiving end receive a strike as if made by a much larger and heavier blade. For such purposes (damage, ease of parry, breaching armor), it strikes as if it were a two-handed sword of great size. The blade, being spirit-forged, is also extremely durable, well stronger then normal bronze.
